Abstract

A methodology for the evaluation of the seismic and landslide risk for urban planning has been implemented and applied at Toscolano Maderno. This methodology considers three different levels of analysis and a multidisciplinary approach due to the different disciplines considered such as the evaluation of seismic hazard, local effects and building vulnerability. For the seismic risk analysis, the first level defines four different risk classes on the basis of the seismic Italian code, the second level identifies the damage scenarios, and the third level considers the seismic risk. With regard to the evaluation of landslide hazards, at the first level it is necessary to identify the landslides and their characteristics (typology and activity), at the second level the aim is to evaluate the slope stability (in static, pseudo-static and dynamic condition) considering the entire analyzed territory and the third level performs the analysis considering the single landslide (in static, pseudo-static and dynamic condition). In the case of Toscolano Maderno, for the seismic risk analysis, the second and the third levels have been applied: the results are produced in terms of building damage, injured people, victims and in terms of average annual expected damage. For the landslide hazard the first and the third level have been applied: the results are produced in terms of a landslide map and displacement on a landslide.
